Need Wheel Bearing Advice

The difference is that auto companies don't use cheap junk for bearings. Auto spindles have a decent amount of lateral support for the inner bearing shoulder, many trailer axles have next to nothing. I have measured angles, inspected races and consulted with a customer that is a grease expert that has a business doing nothing but this very subject. Because I do inspect, measure, lube and adjust, I think that my expertise has more validity than those that say to ignore the issues and pretend that there are none. Of course do whatever you want, my comments are for those that actually want information.
